Tests fail with libxml2 2.15 #468
Description
Debian noticed that the autopkg tests (a type of CI used for repo-wide reverse dependency checks) fail for package xml when libxml2 2.15 is used -- and this now blocks the passage of libxml2 to testing. This is in bug report 1119020 which mistakenly landed in my lap as the difference between CRAN packages XML (which I maintain) and xml2 (this one) was overlooked.
As for the bug, from the console log I can replicate in the rocker/r-base container with libxml2-dev from unstable, it appears one expectation needs an update:
* checking tests ...
